TEAR RESISTANCE

Tear Resistance
is the force required to rip a sample of plastic film, sheeting or rubber product.
An unnicked 90-degree angle specimen is used to measure the tear resistance of foam.

Calculation:

Calculate the resistance to tear from the maximum force registered by the testing machine
and the thickness of the specimen, and express as the force in newtons (or kilogram, pounds-force)
required to tear a specimen 1 m (or 1cm, 1 inch) in thickness.
